What is a fault?
an unattractive or unsatisfactory feature, especially in a piece of work or in a person's character. Also its a crack or a fracture in Earth;s Lithosphere along which one block of rock moves toward, away from, or past another.

how Does the amount of silica in lava affect the flow of magma?
The magma will flow more slowly the greater the amount of silica that is within the lava.

What is cinder cone?
Cinder cone is a small, steep-sided volcano that erupts gas-rich, basaltic lava.
500
What is Secondary Waves?
Secondary waves cause the rocks they pass through to change in shape. These waves are the second fastest traveling seismic waves (after primary waves) and can travel through solids but not through liquids or gases. Also called shear wave , S wave.
500
What is Primary Waves
Primary waves are alternatingly compressional and extensional, and cause the rocks they pass through to change in volume. These waves are the fastest traveling seismic waves and can travel through solids, liquids, and gases. Also called P wave.

Basaltic Magma produces nonexplosive eruptions such as those at?
Kilauea

how does the amount of silica content change the viscosity of magma?
- High silica=high viscosity (thick lava) -low silica= low viscosity (runny lava)
